Revelation 5:11

11 And I beheld, and I heard the voice of many angels round about the throne and the beasts and the elders: and the number of them was ten thousand times ten thousand, and thousands of thousands;

John saw and heard the voice of many angels. Some say the book of Revelation is all symbolic allegory but John tells us what He heard in this book many times. What is heard cannot be made into symbols reflecting some spiritual meaning.

The number of these beings around the throne was over 100 million. We see the same reference to this number of beings around the throne and to the timing of these events in Daniel Chapter 7.

9 I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire. 10 A fiery stream issued and came forth from before him: thousand thousands ministered unto him,  and ten thousand times ten thousand stood before  him: the judgment was set, and the books were opened.

26 But the judgment shall sit, and they shall take away his dominion, to consume and to destroy it unto the end. 27 And the kingdom and dominion, and the greatness of the kingdom under the whole heaven, shall be given to the people of the saints of the most High, whose kingdom is an everlasting kingdom, and all dominions shall serve and obey him.

In Daniel, the Ancient of Days comes to set up his court and there are over 100 million beings as well around the throne. In Daniel and in Revelation we see the kingdom will be taken from Satan and awarded to the saints. Prophetic scripture is consistent and totally reliable.
